摘要：
A method for estimating a greenhouse gas emission from a ruminant (6) in a loose housing environment (1), and in a predetermined time period from T0 to Tdesired, characterized in that the method comprises: - determining a model emission rate function EM(t) for the ruminant, - determining the moments of eating feed by the ruminant, at least during the predetermined time period, as a series of points in time {T1, T2, T3,..., Tn}, - constructing the estimated real emission rate function ER(t) on the basis of the model emission rate function and the moments of eating feed, and - integrating ER(t) from T0 to Tdesired. Also provided is a greenhouse gas emission estimation device (8), arranged to perform this method. In the invention, use is made of the insight that knowing the eating moments can fine-tune calculations for establishing greenhouse gas emissions from the animals.
